I received this Christy Safety Razor in a lot on May 29, 2018. It set silent until I ran across it today. While visiting @Redfisher, he showed me his Christy and said that it would take a Schick injector blade. With that information, I cleaned up the Christy. I will probably take it for a spin soon. Before cleaning. After a Dawn bath and a little scrubbing. These pictures are after a session with Brasso.
You just need to bend the blade holder a little bit so it is tighter. Sent from my SM-S320VL using Tapatalk
